Relative to Unity7 on the Pineview system:
mir_proving_server is much faster than Unity7 (perfect 60FPS compositing
and egltriangle up to 1000FPS).
Unity8 is much slower than Unity7 (only a couple of FPS at most and
sometimes less than 1).
Seems like (similar to mir_demo_client_eglplasma) some advanced shaders
cause the performance to fall off a cliff. It's not obvious where the
edge of the cliff is though, because everything keeps working, just much
slower.
We probably need a shader/GL debugging expert to look into it.

Bug description:
This bug Makes the pc UNUSABLE
when I try to launch Unity 8 and Mir, after writing the password on the login
(in the image attached) the bar to enter the password disappears and my
computer screen stays stuck without them let me do anything. the connection
begins to separate and reattach alone and I can only move the cursor. it makes
the computer unusable and I am forced to restart forced to then enter into
Unity 7. represented in the screenshot is the lock status after entering the
password.
Version: unity8.12+16.04.201604.01.1
Version of Mir : 0.21
